Heat
Temperature regulation is controlled by this structure in the brain
What is the hypothalamus?
This heat gain mechanism is due to contraction of the skeletal muscle
What is shivering?
This hormone is secreted upon altitude exposure due to low levels of oxygen in the blood
What is erythropoietin?
This altitude training model is often used by sea level endurance runners to improve their performance
What is Live High Train Low?
This is the rate limiting enzyme of glycolysis
What is PFK?
These structures within the skin facilitate evaporative cooling
What are the sweat glands?
Cold conditions increase the likelihood of this heartbeat irregularity
What is an arrhythmia?
Due to low arterial oxygen saturation, this component of Fick's Equation decreases
What is the AVO2 difference?
This is the recommend exposure time (min) for altitude acclimatization at 5000m
What is ~2-3 weeks?
The reflex is responsible for reducing the heart rate when blood pressure is high
What is the baroreflex?
This is the most severe form of heat illness characterized by a core temperature exceeding 40C
What is heat stroke?
This is the primary nutrient (energy substrate) in the cold
What is glucose/CHO?`
Due to high blood pressure, this "effect" is observed at the level of the kidney
What is diuresis?
This term refers to adaptation with an artificial environment?
What is acclimation?
This occurs during exercise when the O2 demand > O2 consumption
What is the O2 deficit?
Vasodilation serves the purpose of what heat loss mechanism
This activity within the blood vessels serves to reduce heat loss
What is vasoconstriction?
This refers to the increase in tidal volume nearly immediately upon altitude exposure
What is the hypoxic ventilatory response?
This refers to the increase in red blood count count during altitude exposure
What is erythropoiesis?
The principle that describes orderly recruitment of the skeletal muscle
What is Henneman's Size Principle?
This neurotransmitter of the sympathetic nervous system initiates sweating and vasodilation
What is acetylcholine?
This protein within the brown adipose tissue is capable of thermogenesis
What is UCP1?
This describes a condition of low levels of oxygen in the blood
What is hypoxemia?
This refers to a blunted response to cold environments
What is habituation?
This condition encompasses low energy availability, osteoporosis, and amenorrhea
What is the female athlete triad?
